Need help with environment variables

[Edvinas]

I can't figure out how in Environment Variables dialog (Settings/Environment.../Environment variables) I can reuse already defined environment variables.

For example equivalent of this:
set PRJ_ROOT=C:\Some project
set PATH=%PATH%;%PRJ_ROOT%\bin

Please help

Although I'm not 100% sure what you mean I believe you are asking to support for:

Code

set MY_VAR=%MY_VAR%;OTHER_VAR

This recursion is not (yet) supported. for now you have to setup the complete envvar as required. I'm aware of this issue anyways...
